Description

Technical Field

[0001] The utility model relates to the technical field of medical catheter cutting, in particular to a medical catheter cutting device. Background Art

[0002] A medical catheter is a thin tube made of medical grade material that is inserted into the body to treat disease or perform surgical procedures. It has a wide range of functions and can be inserted into body cavities, ducts or blood vessels, the brain, skin or fatty tissue. Functionally, they allow drainage, administration of fluids or gases, entry of surgical instruments, and also perform a variety of other tasks depending on the type of catheter. The outer tube of a medical catheter is often spliced ​​from multiple tubes of different lengths and different materials, so the catheter needs to be cut.

[0003] According to a medical catheter cutting device proposed by Chinese patent announcement No. CN219337815U, the catheter can be clamped by the mutual cooperation of the lower rotating rod, the slider, the upper rotating rod and the adjusting bolt, and then the position of the cutter can be adjusted by the interaction of the fixed plate, the rotary handle and other structures, so that the catheter can be adjusted and cut according to different length requirements, and the operation is simple and the use is more convenient. Through the mutual cooperation of the slide rail, the sliding plate, the lower clamping plate, the upper clamping plate and other structures, one end of the catheter can be clamped, and then through the mutual cooperation of the lower rotating rod, the slider and the upper rotating rod and other structures, the catheter can be straightened, thereby reducing the damage caused by the bending of the catheter. The size error can make the size of the catheter more accurate when cutting and more convenient to use. The application document can straighten the medical catheter and adjust the position of the cutter. However, in actual use, because the medical catheter is usually made of soft materials, such as silicone or polyurethane, these materials have good softness and elasticity, which are easy to insert into the body channel and reduce stimulation and damage. Therefore, the medical catheter generally has a certain elasticity. In the process of straightening the medical catheter, the application document may cause the medical catheter to be elongated, thereby making the cutting length of the medical catheter inaccurate. Therefore, a medical catheter cutting device is proposed to solve the above problem. Utility Model Content

[0022] like Figure 1-4 As shown, a medical catheter cutting device proposed by the utility model comprises a base plate 1, the upper end surface of the base plate 1 is provided with two linear slide rails 2, the upper part of the two linear slide rails 2 is slidably connected with a gantry 3, the interior of the gantry 3 is provided with a cutting assembly 4, the upper end surface of the base plate 1 is provided with a plurality of placement blocks 5, the tops of the plurality of placement blocks 5 are provided with placement grooves 6, the upper end surfaces of the plurality of placement blocks 5 are provided with fixing assemblies 7, and the front surface of the base plate 1 is provided with a controller 8.

[0023] In the utility model, the gantry 3 can be driven to move forward or backward by two linear slide rails 2, and the gantry 3 will drive the cutting assembly 4 to move forward or backward, so that the cutting position of the cutting assembly 4 can be adjusted, and multiple medical pipes can be placed respectively by multiple placement blocks 5 and multiple placement slots 6. The placement of the medical catheter by the placement slot 6 can ensure that the medical catheter remains straight during cutting, and the medical catheter inside the placement slot 6 can be fixed by the fixing assembly 7 to prevent the medical catheter from shifting during cutting, thereby ensuring the stability of the medical catheter during cutting.

[0024] In an optional embodiment, the fixing assembly 7 includes a U-shaped frame 701, a threaded rod 702, a knob 703, a movable plate 704, a sliding module 705 and a rubber block 706. The U-shaped frame 701 is arranged on the upper end surface of the placement block 5, the threaded rod 702 is arranged on the top of the U-shaped frame 701 and penetrates to its bottom, the threaded rod 702 is threadedly connected to the U-shaped frame 701, the knob 703 is arranged on the top of the threaded rod 702, the movable plate 704 is slidably connected to the left and right side walls of the inner cavity of the U-shaped frame 701, the bottom end of the threaded rod 702 is rotatably connected to the upper end surface of the movable plate 704, the sliding module 705 is arranged on the outer end surface of the movable plate 704, the rubber block 706 is arranged on the lower end surface of the movable plate 704, and the rubber block 706 corresponds to the position of the placement groove 6.

[0025] It should be noted that when the knob 703 is rotated, the knob 703 will drive the threaded rod 702 to rotate. Under the action of the threaded thrust, the threaded rod 702 will move upward or downward while rotating. The threaded rod 702 will drive the movable plate 704 to move upward or downward. The movable plate 704 will drive the rubber block 706 to move upward or downward. The movable plate 704 can be guided by the sliding module 705 to ensure the stability of the movement of the movable plate 704.

[0026] In an optional embodiment, the sliding module 705 includes two sliding blocks and two sliding grooves. The two sliding blocks are respectively arranged on the left and right sides of the movable plate 704, and the two sliding grooves are respectively opened on the left and right side walls of the inner cavity of the U-shaped frame 701.

[0036] Working principle:

[0037] When the medical catheter cutting device is used, the medical catheter is first placed in the corresponding placement slot 6, and then the knob 703 is turned. The knob 703 will drive the threaded rod 702 to rotate. Under the action of the thread thrust, the threaded rod 702 will move downward while rotating, and the threaded rod 702 will drive the movable plate 704 to move downward, and the movable plate 704 will drive the rubber block 706 to move downward. When the bottom of the rubber block 706 abuts against the outer side of the medical catheter, the medical catheter can be fixed, and then the two linear slide rails 2 are started. The gantry 3 can be driven to move forward or backward through the two linear slide rails 2, and the gantry 3 will drive the cutting assembly 4 to move forward or backward, so that the cutting position of the cutting assembly 4 can be adjusted. Finally, the electric telescopic rod 401 is started, and the piston rod of the electric telescopic rod 401 will drive the lifting plate 402 to move downward, and the lifting plate 402 will drive the cutting blade 404 to move downward, and the cutting blade 404 will enter the corresponding placement slot 6, so that the corresponding medical catheter is cut by the cutting blade 404.
